Alignment: The utterdark champion must be of evil alignment. If he ever ceases to be evil, he loses the benefits of his tenebrous smite, touch of corruption, and channel energy abilities until his alignment returns to evil.

Swallow the Light: At 1st level the utterdark champion gains the Dark sphere as a bonus magic talent. If the utterdark champion already possesses the Dark sphere, he instead gains 1 magic talent from that sphere. An utterdark champion may always gain a magic talent from the Dark sphere in place of a bonus combat feat or mystic combat.

This replaces the magic talent normally gained at 1st level.

Tenebrous Smite (Su): At 1st level, whenever the utterdark champion places a darkness effect on an area, he may spend an additional spell point as a free action to empower themselves against any good creatures caught within that darkness. The utterdark champion gains a bonus equal to his Charisma modifier on all attack rolls made against good-aligned creatures caught within the area of darkness. In addition, the utterdark champion’s weapons deal an amount of additional damage equal to 1/2 the utterdark champion’s class level (minimum: 1) to all good creatures.

At 7th level, the utterdark champion may spend 2 spell points instead of 1 to empower his allies against his foes, granting them half of his tenebrous smite bonus; all weapon attacks made by the utterdark champion’s allies against good targets caught within the area of darkness gain a bonus to their attacks equal to 1/2 the utterdark champion’s Charisma modifier (minimum: 1) and a bonus to damage equal to 1/4th the utterdark champion’s class level.

At 13th level, when the utterdark champion empowers his allies against his foes, they gain his complete tenebrous smite bonuses, rather than 1/2 his bonuses.

This replaces resist magic

Touch of Corruption (Su): Beginning at 2nd level, an utterdark champion may surround his hand with a fiendish flame, causing terrible wounds to open on those he touches. Each day he can use this ability a number of times equal to 1/2 his mageknight level + his Charisma modifier. As a touch attack, an utterdark champion can cause 1d6 points of damage for every two mageknight levels he possesses. Using this ability is a standard action that does not provoke attacks of opportunity. Alternatively, an utterdark champion can use this power to heal undead creatures, restoring 1d6 hit points for every two levels the mageknight possesses. This ability is modified by any feat, spell, or effect that specifically works with the lay on hands paladin class feature. For example, the Extra Lay On Hands feat grants an utterdark champion 2 additional uses of the touch of corruption class feature.

At any time, the utterdark champion may spend a bonus combat feat or mystic combat to gain an antipaladin cruelty, using his mageknight level as his antipaladin level for this purpose.

This replaces the mystic combat ability gained at 2nd level.

Channel Energy (Su): When an utterdark champion reaches 4th level, he gains the supernatural ability to channel negative energy like a cleric. Using this ability consumes two uses of his touch of corruption ability. An utterdark champion uses his level as his effective cleric level when channeling negative energy. This is a Charisma-based ability.

This replaces the combat feat gained at 4th level.

Unholy Champion (Su): At 20th level, an utterdark champion becomes a conduit for the might of the evil and dark. He gains DR 10/good, and increases the bonus damage gained through his Tenebrous Smite ability from 1/2 his mageknight level to his mageknight level. In addition, whenever he channels negative energy or uses touch of corruption to damage a creature, he deals the maximum possible amount.
